Elastomer dienic acid amends carrier coupling silanol functions, process for its synthesis and rubber composition comprising it.

The present invention relates to a modified diene elastomer mainly comprising a case coupled by a group carrying a function comprising a predominantly hydrolyzed silicon atom silanol and an amine function, related to the diene elastomer via the silicon atom and its synthesis process. This elastomer has the distinction of not undergo changes in Mooney viscosity during storage.
